A) closed to night and open during the day
B) closed during the day arid open at night
C) never closes
D) never opens
Correct Answer: B
Solution :
CAM stands for Crassulacean Acid Metabolism which is a mechanism of photosynthesis involving double fixation of \[\text{C}{{\text{O}}_{\text{2}}}\text{.}\]It occurs in succulent plants belonging to Crassulaceae, cacti, euphorbias etc., where the stomata remain closed during daytime and open only at night. Crassulacean plants have this unique mechanism to perform photosynthesis without much loss of water. They perform acidification or dark fixation o\[\text{C}{{\text{O}}_{\text{2}}}\] during night (phase-I) and deacidification (phase-Ii) during day to release \[\text{C}{{\text{O}}_{\text{2}}}\]for actual photosynthesis.
